Molecular orbitals are formed through a linear combination of atomic orbitals
Is it true that molecular orbitals are formed through a linear combination of atomic orbitals?
Yes. Molecular orbitals are standardly formed through a linear combination of atomic orbitals, a foundational concept robustly supported across quantum chemistry and solid-state literature.
Verdict: SUPPORTED · 5 sources for, 0 against · Last checked
The claim is a fundamental textbook principle of quantum chemistry (LCAO-MO theory). The retrieved papers consistently apply, discuss, or build upon the linear combination of atomic orbitals (LCAO) framework to construct and analyze molecular orbitals across various chemical systems. None of the papers refute the claim.
